The following members return DateEdit objects:
Remarks
The DateEdit allows users to enter a date. The image below illustrates an account form that allows a user to enter a birth date.
The editor initially displays a date icon on the right within the box. You can also add the following optional elements:
1. Custom Icon 2. Label 3. Date Icon 4. Help Text 5. Error Message
Date
Use the Date property to set or get the date in the editor. The MinDate and MaxDate properties specify the minimum and maximum allowed dates and limit user input to the specified range.
Use the DateChangedCommand and DateChangedCommandParameter properties to specify a command executed when the date changes. You can also handle the DateChanged event to respond to date changes.
Use the following properties to change the appearance and alignment of the date in the box:
Property | Description |
|---|---|
Specify the text color for each state of the editor. | |
Specify the font settings of a date displayed in the editor. | |
Gets or sets the horizontal alignment of a date displayed in the editor. |
Date Format
The DisplayFormat property defines the format of a date displayed in the editor.
You can use standard or custom format specifiers (see the MSDN topics Standard date and time format strings and Custom date and time format strings) to create format patterns, for example:
<dxe:DateEdit DisplayFormat="d"/>
<dxe:DateEdit DisplayFormat="ddd d MMM"/>
Date Picker
A date picker appears when a user taps the editor. The default date picker is the same on iOS and Android, which ensures a consistent look and feel for your app on both platforms.
To invoke the picker in code, use the IsPickerShown property.
Appearance Customization
You can customize the appearance of the following visual elements in the calendar: days, months, years, days of the week, and header. You can set a custom style for all such visual elements, as well as for specific days/months/years. A style allows you to specify background and foreground colors, and fonts. You can also replace the default data template used to render a visual element.
- Month View
- Year View
- Decade View
- Calendar Header
- Day of Week
- Day
- Trailing Day
- Month
- Year
The table below contains options that you can use to apply custom styles and templates to visual elements.

if(e.Date.Month == 2 && e.Date.Day == 14) {
e.FontAttributes = FontAttributes.Bold;

}
if(e.Date.Month == 2 && e.Date.Day == 21) {
e.FontAttributes = FontAttributes.Bold;

e.EllipseBackgroundColor = Color.FromRgba(textColor.Red, textColor.Green, textColor.Blue, 0.25);
e.TextColor = textColor;
}
}
<dxe:DateEdit PickerCustomDayCellAppearance="CustomDayCellAppearance"/>
Example 3
The example below shows how to apply a custom appearance to weekends (days in the calendar and days of the week).
using DevExpress.Maui.Editors;
void CustomDayCellAppearance(object sender, CustomSelectableCellAppearanceEventArgs e) {
if (e.Date.DayOfWeek == DayOfWeek.Saturday || e.Date.DayOfWeek == DayOfWeek.Sunday) {
e.TextColor = Color.FromHex("F44848");
if(e.IsTrailing)
e.TextColor = Color.FromRgba(e.TextColor.Red, e.TextColor.Green, e.TextColor.Blue, 0.5);
}
}
private void CustomDayOfWeekCellAppearance(object sender, CustomDayOfWeekCellAppearanceEventArgs e) {
if(e.DayOfWeek == DayOfWeek.Saturday || e.DayOfWeek == DayOfWeek.Sunday)
e.TextColor = Color.FromHex("F44848");
}
<dxe:DateEdit PickerCustomDayCellAppearance="CustomDayCellAppearance"
PickerCustomDayOfWeekCellAppearance="CustomDayOfWeekCellAppearance"/>
Native Picker
The editor can also use a native picker, which varies depending on the platform. Enable the UseNativePicker option to display the platform-specific picker.
Note
Customization options described above are only in effect for the default picker.
Label
The LabelText property specifies the editor’s input prompt string. The label is displayed inside the editor while the editor is not focused. When the editor gets focus, the label moves to the top. If a value is assigned to the editor, the label is always displayed at the top.
To pin the label to the top of the editor, set the IsLabelFloating property to false.
To customize the label’s appearance, use the following properties:
Property | Description |
|---|---|
LabelColor / FocusedLabelColor | Specify the label’s color for each state of the editor. |
Specify the label’s font settings. |
Placeholder
A placeholder (PlaceholderText) is the input prompt string displayed within the edit box when the editor is empty and focused.
To specify the color of the placeholder text, use the PlaceholderColor property.
Help Text and Error Message
You can display the following labels below an editor:
- HelpText - A brief editor description.
- ErrorText - A message shown when an error occurs (HasError is true).
The BottomTextTopIndent property specifies the indent between the editor’s bottom border and the help or error text.
To specify the color and font attributes for the help/error text, use the following properties:
Property | Description |
|---|---|
Specify the help text color for different states of an editor. | |
Specifies the error message text color. | |
BottomTextFontSize | Specify font settings. |
If HelpText is not set, ErrorText appears as an additional line below the edit box and page content shifts down. To prevent this behavior, set the ReserveBottomTextLine property to true.
Autofill
If the editor’s AutofillContentType property is set to AndroidBirthDate or AndroidCreditCardExpirationDate, the user can automatically fill the editor with an appropriate date. Note that the device should have an enabled autofill service that contains the required values (names, dates, passwords, and so on).
Icons
The date editor can display icons within its box.
- Date icon - indicates a date editor.
- Clear icon - removes a date selected in the editor.
- Error icon - appears in the error state (HasError is
true). - Custom icons - can be shown on the left or right within the box.
Use the following members to manage the editor’s icons:
